Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the system architecture?Multi-layered network comprising generation, high-voltage transmission, and lower-voltage distribution
2. What is the primary function?To reliably and efficiently deliver electrical energy from producers to consumers
3. What is the electrical grid and why is it important?The electrical grid is a network that carries electricity from power plants to homes, schools, and factories. It powers lights, toys, computers, and many machines we use every day. Without it, hospitals, phones, and factories would not work.
4. How did the electrical grid start?It began in the late 1800s when Thomas Edison built a DC power station in 1882. Later, Nikola Tesla and George Westinghouse invented alternating current, which could travel long distances and made the grid possible.

Alternating Current (AC): An electric current characterized by periodic reversals in direction, enabling efficient long-distance power transmission.
Transmission Lines: High-voltage conductors designed to transport electricity over significant geographical distances from power generation sites.
Substation: An electrical facility that contains switching and transformation equipment to manage voltage levels for distribution.
Smart Grid: An modernized electrical grid that uses digital technology to improve efficiency, reliability, and sustainability.
